In addition to all of the other good advice, you should know that it's perfectly feasible to batch-process raw files, making shooting a large number of raw files not especially different than shooting jpeg. For example, in Lightroom I routinely apply processing as the files are brought into the system - it's pretty much transparently like shooting jpeg, although I think the system does more actual work. That way you still have the flexibility of raw with the convenience of a more-or-less finished image.
I shoot 20-25k images per year and essentially all of them are raw, with no particular excessive overhead.
